imager.correct - Function

Description By default, imager makes images from the CORRECTED_DATA column. This tool function copies the data from the DATA column to the CORRECTED_DATA column. The main correction that sometimes must be made is for parallactic angle rotation.

Note that correct is automatically invoked whenever MeasurementSet without a CORRECTED_DATA columns is loaded (usually the first time it is processed in imager).

Arguments

`doparallactic`	`in`	Do the correction for parallactic angle?
		`Allowed:`	`Bool`
		`Default:`	`T`
`timestep`	`in`	Time step for corrections
		`Allowed:`	`Quantity`
		`Default:`	`'10s'`

Returns Bool

Example

m:=fitstoms('3C273XC1.ms', '3C273XC1.fits'); m.close()
imgr:=imager('3C273XC1.ms')
imgr.correct(T, '1s')
imgr.clean(model='3C273XC1.clean.model')
